need help on fork() and exec()

Good day

Can anybody assist me on my C project?I gotta write a C program to create a new process and within that new process execute a given function,and it focuses on the usage of system calls fork() and exec().

The user should be able to input and specify a pathname of a file to be executed and the required arguments or a string indicating the end of the run.The program should fork a child to execute the required program.

Really need the answer A.S.A.P...thanks a lot!
